What was the answer for the last question ?? The final answer, attenuation per unit length ??

what did u guys get for the simple harmonic question for the displacement at half kinetic energy

Nice! What about the one where u had to find the velocity of the particle using v= (sqrt) Vq/m, to see if the particle would hit the other particle?

i used the formula backwards and got a pd smaller than 470 then wrote that it wont collide. you? how about the temperature sensing circuit, i got nonlinear

Oh ok, I used the formlula backwards too but to find the velocity that the particle should have if it were to collide. As the required velocity was bigger than the one they suggested, I said that it won't collide. Uhm... yeah non-linear variation!

nice i hope i wont be penalised for working backwards though. how about the ideal gas temperature question, i got 356 but found it confusing

No I think working backwards was the only way to answer that question. Yeah I also got 356 K, and I also found it confusing. First I thought of using PV/T=PV/T but that didn't work out. And 356 K seems reasonable compared to the initial temperture they gave us of 300K.

yeah same, my working was so untidy cause i kept cancelling out, the pressure in container B must have been distractor information
